This invention relates to bed bottoms and more particularly to improvements in top surface border construction for bed bottoms. The invention also relates more particularly it to the type of bed bottoms in which the top surface is formed by means of the large end coils of a plurality of spiral cone shaped springs which are arranged with their large end coils disposed in the plane of the top surface of the bed bottom.

The principal objects of the invention are i to provide an improved top surface border construction which will be strong and rigid to withstand such strains as bed bottoms are often subjected to in shipment or other handiing; to provide an improved border construction which will be neat in appearance; to provide a border construction which is free from projecting parts or other parts which are liable to cause injury to the person or to the bedding; to provide a border conlit struction-which will be effective to support the top coils of the outer row of springs in the desired plane without impairing to a material extent, the resiliency of the bed bottom; to provide an improved construction which will be simple and economical to manufacture, and in general, to provide an improved construction of the character referred to.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawing in which drawing I have illustrated a portion of a bed bottom embodying one form of the invention.

In the drawing:,

Fig. 1 is a plan, and

Fig. 2 is a section on the line 22 of Fig. 1.

Referring now to the drawings, the bed bottom shown in the present instance includes an angle iron member which constitutes the side border member of the main supporting frame. Spring supports or slats 11 which extend across the main supporting frame that is, from side to side of the frame are provided forsupporting spiral springs 12. The slats 11 are preferably formed of metal straps having end portions disposed horizontally as shown at 13 and overlying 195th. serial I la. 532N366.

and riveted to the horizontal flange of the angle iron member 10, as'shown at let. The slats 11 are bent downwardly as indicated at 15 and also as'shown at 16 to form depressed horizontal intermediate portions 17 which are adapted to receive and support double declr spiral springs in a manner well known in the art. The slats are preferably twisted through an angle of 90 as indicated at 18, so that the intermediate portions of the slats are verticallyidisposed and thereby enabled to better support the double deck springs.

The outer row of spiral springs along the sides of the bed bottom are preferably single deck cone shaped springs, as clearly shown in Fig 2, the smaller ends of which are seated on the horizontal end portions 13 of the slats and secured thereto by suitable means such as clips, as shown at 19. The

large top end coils 20 of the springs are disposed in the top surface of the bed bottom and are preferably connected together by means of crossed helicals 21 and 22 which serve to maintain the coils in substantially axial vertical position while at the same time permitting the springs to yield as desired.

The top surface of my improved bed bottom is provided with a border or marginal frame to which the top coils of the outer rows of springs are connected so as to prevent the helicals from pulling the springs out of substantially axial vertical position. The marginal frame for the top surface of the bed bottom is indicated at 23 and comeach of the top coils of the outer rows provided with a U-shaped part or loop member 26 which projects outwardly from the top coil and lies under the relatively wide metal strap or horizontal flange .24, as is clearly shown in the said Fig. 2. Preferably, the outer end of the loop'% extends Fifi - to prevent bedding from being trapped beover the top surface of the horizontal flange,

tween the flange and loop with consequent possible injury to such bedding. This construction also prevents noise incidentto rela 'tive movement between the marginal frame and top coil from developing as is quite possible, and as often occurs in many of the 'commerciallyju'sed structures of the prior art.

The rivet clamping member 27 includes an enlarged head part 28 which forms the clamping member proper, and means for uniting the clamping member 28 to the marginal frame. This means is in the form of a shank 29, which extends upwardly from the clamping member, through the loop 26 and through a suitable aperture 30 provided ,in the horizontal flange and which shank is headed as indicated at 31. The shank part 29 extends through the loop preferably at its outer end as best shown in' Fig. 2 so as to anchor the top coil against inward horizontal shifting movement relative to the horizontal flange 24 of the marginal frame. The vertical flange 25 of course prevents horizontal shifting of the top coil in an outward direction. The head or clamping member 28 proper is preferably' of such a dimension that it underlies substantially the entire length of the portion of the loop 26 which underlies the horizontal flange 24:.

It will be understood that by making the clamping member 28 of the dimension above indicated, the part of the loop 26 under the inner edge of the horizontal flange will be prevented from working away from the horizontal flange thereby overcoming such dis advantages as are present in structures where fore be construed as broadly as possible, con-' sistent with the state of the art.

I claim as my invention:

In a bed bottom, the combination of a lower frame, an outer row of axially vertical springs consisting of a plurality of similarly shaped turns of wire mounted on said frame and provided with relatively large end coils at the top surface of the bed bottom, a marginal frame for said top surface comprising a rigid strap angular in cross-section, means for securing said top coils to said strap comprising parts projecting from said top coils and contacting with one surface of said strap, clamping members engaging said-projection, and means uniting said clamping members to said strap so as to retain said projections in tight engagement with one side of said strap.

' ERWIN L. KLOS.

the top coils are secured to a marginal frame in such a way that they may move freely relative thereto. In the present instance, the clamping member 28 is a circular member as indicated in broken lines in Fig. 1 and is effective to clamp the projecting coil parts 26 against the horizontal flange 24 at points spaced crosswise as well as lengthwise of the bed bottom Accordingly, the top coils are held against excessive tipping or twisting while at the same time permitting the coils to yield sufliciently torform an exceptionally desirable bed bottom.

I am aware that changes in the general a rrangement as well as in the details of construction may be made without departing from the spirit of the invention, the scope of which should be determined by reference to the following claim which should there- DISCLAIMER 1,732,81'4.E'rwin L. Klos, Kenosha, Wis. BED BOTTOM. Patent'da'ted October 22, 1929. Disclaimer filed October 29, 1920, by the assignee, Simmons 00mpany.' Disolaims from the scope of the claim of said patent any structure with springs having generally circular top end coils Where any material portion of the general curve of said top coils extends outside of the area bounded by the line of the inner edge of the horizontal flange of the border angle, and

Limitsthe scope of said claim to a structure in which the parts projecting from said top coils comprise relativel narrow loops of such length as to position the general curves of the said top coi s within the area bounded by the inner edge of the horizontal flange of the border angle.
